Don't worry. I remember when legislation was introduced against hate speech. People carried on about how it would be end of everything and it wasn't.
If its not a constitutional law it'll simply go to court and be overturned.
But in the meantime, it is my armchair belief that the test is to demonstrate a pattern of behaviour that seems targeted and premeditated with the intent to cause harm, not 1-off statements that aren't repeated.
Easy way to avoid problems with this and other things is to focus on the issue and not the person. If there is an issue then talk about that, don't make issues about the person if you can, because then it becomes hard to have dialogue.
